Alt Crossens catchment

The Alt Crossens area is low lying, with considerable areas of high grade farmland, and approximately 28% of the area is urbanised. The hydrology of the area is complex because much of the catchment is at or below sea level. Ultimately, heavy reliance is placed upon the two main pumping stations of Altmouth and Crossens to evacuate water from the Alt and Crossens catchments respectively. There is no capacity for gravity drainage from the Crossens catchment, although within the Alt catchment, there is some scope for gravity drainage during low tide at Altmouth. (EA)
